When it comes to ARs, pivot and takedown pins are nothing special. They are generally the standard mil-spec ones that do the same thing all the others do. Some companies have created some with dimples to help pull them to the open position, some make them lock with a small detent, and then we have Xtreme Precision that made some extended pivot and take down pins. I’m not usually one to add extended parts on my rifle but sometimes you come across a worthwhile addition that gives you an edge or just makes things slightly easier. The Xtreme Precision Extended pivot & Take Down Pin built for the AR15 style rifles may just be one of those worthwhile additions.
